An industrial temperature sensor uses an unsigned 6-bit register to store integer offsets. The maximum value this register can represent is 631063_{10}6310 (or 1111112111111_21111112).
Identify which of the following 6-bit unsigned binary additions will result in an arithmetic overflow error in this register.
101100 + 001010
110011 + 001101
011101 + 011110
101010 + 010101
